Checking for display problems on your new PC setup
You're correct about the TDF and the need for a new PSU. Regarding your question, yes, you'd typically lose around 80% of the power output, so the effective wattage would be reduced. The PSU's wattage would reflect this loss, not an additional draw.
I've read it again, but the idea still doesn't click. You mentioned the recommended wattage for a PSU, and people faced issues with their units at those levels due to spikes that triggered OCP on atx3.0 models. A common fix was to upgrade to a higher-wattage unit or opt for a 3.1 PSU. I know efficiency drops as power increases—like an 850W PSU being less efficient than a 750W one, which in turn is less efficient than a 700W model. I own a PSU tester, but it only checks voltage accuracy against the label. I’m unsure if my unit has three, two, or just one rail. My card uses two 8-pin ports, so I used two power cables; if it really has three rails, it’s likely using two of them. It seems to work, though it’s heavily underclocked and undervolted—only drawing around 150W at load and 30W when idle. I think my PSU could handle more power.
This was a new experience for me regarding the OCP flipping. It's my first build, so I wasn't expecting any problems. I checked for the issue where the OCP triggers kernel 41 errors and found a suggestion to change the PCIE connector. After making that change, I didn’t notice any crashes. My benchmarks are looking good so far. I’m considering upgrading my PSU to prevent future issues. Would an 850 80+ Gold work for me? I have a Ryzen 5 5600X, Gigabyte B550M, RTX 2060, two 8GB 3200 DDR4 RAM modules.
It would be more than sufficient for the year 2060. An 850w setup is suited for high-end components like amphora and RDNA2. Speeds around 3080s and 6900s are typical. Lovelace and RDNA3 are still in development, but I’m not sure about their needs. I purchased RDNA2, which should work well with the 2060. A video about low-end graphics cards was posted recently—maybe helpful or not.
